 DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
With reference to FIG. 1, an electrical connector (1) in accordance with the present invention comprises an insulating base (10).
The insulating base (10) has a side and a plurality of slots (11) and may be a rectangular solid. The slots (11) are spaced along the side of the insulating base (10). Each of the slot (11) has a conductive terminal (20).
Each of the conductive terminals (20) are metallic and bent and has a first end protruding up from the insulating base (10) and a second end extending away from the insulating base (10) and may have a mounting portion (21), a contact portion (22) and a pin portion (23). The mounting portion (21) is U-shaped and mounted in a corresponding slot (11) of the insulating base (10). The contact portion (22) is formed on and extends up from a top end of the mounting portion (21) and protrudes out from the insulating base (10) and may be implemented as the first end of the conductive terminal (20). The pin portion (23) is formed on and horizontally extends forward from a bottom end of the mounting portion (21) under the contact portion (22) and has an unbent free end and may be implemented as the second end of the conductive terminal (20).
With further reference to FIG. 2, the electrical connector (1) is implemented as a component of a computer peripheral device. The computer peripheral device may be a mouse and further has a base (30), an electrical connector (1), a printed circuit board (40) and a cover (50) in addition to the electrical connector (1).
The base (30) has a mounting slot (31). The mounting slot (31) corresponds to and receives the insulating base (10) of the electrical connector (1) and has a front opening exposing the side of the insulating base (10) and the pin portions (23) of the conductive terminals (20) of the electrical connector (1).
With further reference to FIG. 3, the printed circuit board (40) is mounted on the base (31), located above the insulating base (10) within the computer peripheral device, electrically contact to the first ends of the conductive terminals (20) and may have a plurality of signal contacts (41). The signal contacts (41) are formed on a bottom surface of the printed circuit board (40) and respectively abut the contact portions (22) of the conductive terminals (20). Since the contact portions (22) protrude out from the insulating base (10) and the conductive terminals (20) are metallic and has a little elasticity, therefore the contact portions (22) can tightly contact the signal contacts (41) when the printed circuit board (40) is mounted on the base (30).
The cover (50) is mounted on the base (30) and covers the printed circuit board (40) and the electrical connector (1).
With further reference to FIG. 4, since the printed circuit board (40) securely connects with the electrical connector (1), the second ends of the conductive terminals (20) may electrically couple to a cable (60) of the computer peripheral device. The cable (60) then electrically connects to the printed circuit board (40) via the conductive terminals (20) to transmit signals. The cable (60) may have a plurality of leads (61 a) extending from an end of the cable (60) and the pin portions (23) are for being respectively soldered to the leads (61 a) of the cable (60). With further reference to FIG. 5, the cable (60) may have a plug (61 b) having a plurality of pins respectively corresponding to the pin portions (23).
In conclusion, the electrical connector (1) facilitates the connection between the printed circuit board (40) and the cable (60) and has advantages of low cost and assembling time-saving and may be able to be applied in automation manufacturing to increase productivity of computer peripheral devices.
Even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and features of the invention, the disclosure is illustrative only. Changes may be made in the details, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
